You can also specify a custom color by using a hexadecimal number, preceded by the pound character (#), in the form #RRGGBB. RR, GG, and BB represent hexadecimal values from 0 to 255 that indicate the red, green, and blue components of a color, respectively. For example, the value #0000FF represents the color blue. It specifies the minimum value (00) for the red and green components, while specifying the maximum value (FF) for the blue component.
